Very severe acute asthma (termed "near-fatal" as there is an immediate risk to life) is characterised by a peak flow of less than 33% predicted, oxygen saturations below 92% or cyanosis (blue discoloration, usually of the lips), absence of audible breath sounds over the chest ("silent chest" : wheezing is not heard because there is not enough ...
When a patient with pneumonia is an alcoholic, the mortality rate exceeds by 50% if they are placed into intensive care (ICU). According to Kershaw, C 2008 page 1, "[a]s of 2001, pneumonia was the sixth most common cause of death in the United States".
When combined with inhaled steroids, β adrenoceptor agonists can improve symptoms. [1] [2] In children this benefit is uncertain and they may be potentially harmful. [2]They should not be used without an accompanying steroid due to an increased risk of severe symptoms, including exacerbation in both children and adults. [3]
The mainstay of treatment is corticosteroids such as prednisolone, with immunosuppressant medications such as azathioprine, and mycophenolate added in some cases. Some patients may require oxygen as their disease progresses.
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
And, severe asthma attacks can be life-threatening. Asthma can be treated using medications, lifestyle treatments, and inhalers. Inhalers are handheld devices that get medicine directly into ...
U.S. government researchers have found that a widely prescribed asthma drug originally sold by Merck & Co may be linked to serious mental health problems for some patients, according to a ...
AERD affects an estimated 0.3–0.9% of the general population in the US, including around 7% of all asthmatics, about 14% of adults with severe asthma, and ~5-10% of patients with adult onset asthma. [2] [3] [8] AERD is uncommon among children, with around 6% of patients, predominantly female, reporting disease onset during childhood. [9]
